I have had the good fortune of operating this Crown Reach Truck with a seat. No seat belt tho', and it IS quite easy to step off in case of a tipover.

The BT's have the same configuration as well. All I have ever come across are the older ones and they have no seat belts either. Again, it is quite fast and easy to jump out.

However, the sit-down is not as easy as one must clear the steering wheel, then turn sideways, and either slip or push oneself out, and in that time, the truck has indeed tipped, trapping the poor operator between the truck and the ground.

Much easier in the sit-down reach trucks. They are sitting sideways. The truck is not going to tip backwards unless they are falling off a loading dock backwards.
